The existence of flexible sandstone appears to have been known of since 1780, when specimens were brought to Europe from Brazil hy the Marquis of Lavradio, Viceroy of Rio de Janeiro. The bed-rock in which the flexible sandstone occurs was found by Von Eschwege to be largely dereloped near Mt. Itacolunmi in the State of Villa Rica, Province of Mina Garaes, Brazil, and is described by him as a fissile sandstcme containing plates of talc, chlorite, and mica.This rock contains a little gold, and has been shown by Heusser and Claraz to be the parent source of the Brazilian diamond.
